Originally posted by paulh You might think about picking up an O-ME53 eyepiece magnifier. My K100D also has a dim & smallish viewfinder & the O-ME53 is a huge help when doing MF. It doesn't improve the VF brightness, but the larger view makes MF quite a bit easier for me.
Finally got one direct from Ricoh in Germany - turns out to be cheaper than any shop I could find. Definitely a good investment, it also extends the eyepiece by quite a bit and makes it a lot easier for me as I wear glasses. Thanks for the tip
